NASA Tests RS-25 Engine of the Space Launch System

NASA conducted developmental testing of its new rocket engines at the Stennis Space Center in Mississippi. They ran a series of tests for the main rocket engine that will launch the Orion spacecraft into space and eventually to Mars.

The RS-25 engine was tested for nearly 9 minutes and everything went as expected. The Space Launch System will consist of four RS-25 engines for the core stage and two five segment solid rocket boosters. Just one of the RS-25 engines produce 512,000 pounds of thrust which is equivalent to 12 million horsepower!

In terms of size, the RS-25 is about the same weight and size as two F-15 jets but produces eight times more thrust.

“The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system for deep space exploration. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time. Aerojet Rocketdyne of Sacramento, California, is the prime contractor for the RS-25 engine work.” NASA said Thursday.
